citizen.ofltlie United state's, residing at La ing and longitudinallyfor use Crosse,finthej county of La Crosse and State of 'Wisccn'sin;have invented certain new and useful" Improvements in Pin-Tumbler Locksand I; do hereby declare the following to be a full, lear, andexactdescription of the invention, such 'as will enable others skilledin the art to which "it appertains't-o' ma keanduse the same; v i

y invention relates toan improvement in pin tumblerlocks designedparticularly devices having sliding closures, and it consists in a pintumbler lock'having a revolvmovable plug. i I It further consists in a."pin tumbler lock 'having a revolving andlongitudinally movable plug'thelatter being retained in its locked positionboth "when retracted andprojected. j 4 p It further consists in the parts and combination ofparts as will be more fully describedand pointed out i'n'the claims.

1 represents a face plate carrying the lock cylinder 2, which isprovided with a cylindrical 'bore. for the plug 3, and with ;holes' orrecesses arranged to aline with similar holes in the key'plug 3, for thereception of the pin tumblers 4, which latter are of the Well knownconstruction and are operated by the key in the usual manner. The plug3, is cylindrical in shape and is provided with a key way extendingthroughout part of its length, and it is longer than the cylinder sothat when. in its locking position it 'orojects through the plate andintov the keeper 5, and when retracted or unlocked, its inner end restsflush with the face plate, while its-front end projects at the front ofthe cylinder. Projecting -froin the side of the plug 3 is the stop 6which litter rests in the slot 7 formed in the wall. of the cylinder 2,and limits therotaryas well as the longitudinal movement of on showcases or "other structures or" view showing the bolt retractplate issecured to one member sfrarusrarnnr OFFICE.

Application filed June 1Q, 1912. Serial No. 703,726;

the plug: This slot 7 ektends lengthwise the cyliiider-and is pro vid'edat each end wit-h an extension 8 extending at right angles to the slot-7 so as to permit the plug 3 to make a partial rotation.

In operating the .lock t-he key 9 is int-roducedinto the key slot 10. inthe plug 3 and turned as far as will permit. This movement of the keyturns the plug-and carries the sections of the pin tumblers 4 ment withthe recesses in the cylinder, and permits the plug to be movedlongitudinally 'until'the stop 6 is,in alinement with thecircumferential slot 8 at the opposite end of longitudinal slot 7, andby now turning the key and plug, the latter will be partly rotatedandNcarry the sections of the pin tumblers ,within the plug intoalinement with tumbler recesses in the cylinder,-so that the plug willagain be locked against any movement exceptiwhen released by its key.This longitudinal movement of the plug 3 Within the cylinder,necessitates the employment of a greater number of tumbler recesses anddrivers. in the cylinmr 52 than there are tumblers in the plug 5 and inthe present instance I have shown the cyl inder provided with two pintumblers and the cylinder with-four recesses and drivers. 7 It isnecessary to hate two difi erent pointsatwhich the tumblers may be setinorder to remove the key in the projected and retracted, or locked andunlocked position o the plug, but a particular number of such recessesand tumblers is not material hence I would have it understood that I dnot confine myself to the particulu" nu herein shown. v

This improvement is especially idapted for sliding closures such as showw1nkeeper dow sash, etc., and when applied ii of the structure and theface plate car ying the lock, is secured to the overlappin "'iember 12with the plug 3 of the lockir .e with the opening in the keeper 5. Byinserting the key and manipulating the plug as ab'ovc described, the endof the plug will be projected into the opening in the keeper and thuslock, both members, against air: movement, and by again manipulatingSihe key to retract the plug, the keeper i leased and thus free thesliding 11 1 .1- members of the structure.

within the plug, out of alinethe circumferential slot- 8 of a cylinder,

It is evident that many slight changes might be resorted to in therelative arrangement of parts shown and described withoutdeparting fromthe spirit and scope of my invention. stood that I do not wish toconfine myself to the exact construction and arrangement of partsh'erein shown and described, but

Having fully described my invention what I 'claim as new and desire tosecure by Letters latent, is.:-

1. In a pin tumbler lock, the combination a plug having a semi-rotaryand longitudinal movement within the cylinder and pin tumblersfor'looking the plug in its two positions.

2. Ina pin tumbler lock, the combination of a cylinder, 9. combined kelocking bolthaving a longitu inal and a semi-rotary movement within saidcylinder and tumblers for locking said combined key plug and lockingbolt; in its locking and also in its retracted positions.

3. In a pin tumbler lock, the cdmbination of a cylinder having a seriesof pin tumbler recesses and provided with a lon Hence I would have itunderplug and 'tudinal slot and a circumferential slot at eac end of thelongitudinal slot, in key plug having a semi-rotary and longitudinalmovement in said cylinder and provided withia' pin tum: bler for eachtworecesses in the cylinder,

and also provided with a stop resting and moving within the slo'ts inthe cylinder;

4. A lock for a sliding closure comprising a keeper, a face plate, acylinder carried by the face plate, a combined. key plug and lockingbolt having a longitudinal and semirotary movement within the cylinderwhereby it may be moved into and out of engagement with 'said keeper andtumblers for locking said combined key bolt in its two positions.

In testimony whereof, I have signed this specification in thepr'esenceoftwo subscribing witnesses.
